Thermodynamic properties of the alkali metals

Abstract

The a va ilable data on the thermodynamic properties of the elem ents lithium, sodium, p otassi um, rubidium, a nd cesium have been analyzed, a nd selected values of these properties are presented in tabular form. The tables inclu de valu es of the free-energy function, (F°-HO)/ T ; heat-content function, (H O-H a) / T; entropy, S o; heat content, (l-I°-H a) ; heat capacity, C~ ; heat of formation, !!.l-Ij" ; free energy of format ion, !!.Fj"; and logarithm of tlle equilibrium constant of formation, log Kf , for the solid, the liquid, and the monatomic a nd diatomic gases as a function of temperature from 0° K to high temperatures.
